Well it is kind of hard searching for problems so I am posting mine up. I have a Series 2 Toshiba SD430 (something like that). It is running w/o a cable box. Recently, it started acting up (pixelation and DVD stopped loading) until finally it would no longer display picture or sound. The screen stays black but has a slight static blip every now and then. I bought a replacement drive and installed it. Still no go. The screen says Welcome Powering up (gray screen white letters) , then after 3-4 minutes it goes black - no sound, no video, TiVO central doesn't come on, nothing. It did flash really quick at one point an orange screen with the TiVO logo on it but then went back to black. If I unplug the TiVO, I can watch TV with the cables routing through the in/out of the TiVO. I had thought that that part might be bad, but I guess this rules that out. What is the possibility if installing a new bad HD, I think 1%? So what do you think i9s wrong with my TiVO? Never realized how much I apprecaited this thing until it died on me, now I'm staying up late watching shows, I think I'll have to try to figure out the VCR thingy.
